Problems solved by technology
Traditional lashing systems also require a lot of time to tie the wires to individual brackets
Furthermore, with current orthodontic binding systems, there is great difficulty in controlling the friction between the binding wire and the archwire
Although mechanical latch systems with movable fixed arms make it easier to position the arch wire in the bracket slot, they are more expensive
Additionally, the existing mechanical latch system obscured one side of the tray, making it difficult for the clinician to adjust and keep the area clean

Embodiment Construction
[0023] An exemplary lashing system 10 according to the present invention is schematically shown in the accompanying Figure 1a and 1b middle. As shown, the lashing system 10 generally includes a central block 12 in which a securing plate 14 is embedded. The fixing block may be formed from virtually any material, but rigid or semi-rigid plastic materials (eg nylon) are preferred. The fixing plate 14 is most preferably a curved plate formed from metal or plastic material. The curvature of the fixing plate 14 is concave when viewed from above. Thus, the end fastening edges 14-1, 14-2 of the fastening plate 14 extend outwardly and upwardly from the central block 12 to terminate in the central block 12 at a position vertically above the buried central region 14-3 of the fastening plate 14 place. As seen in side view (see Figure 1b ), the end fixing edges 14-1, 14-2 of the fixing plate 14 point upwards. Spikes 16 may optionally be arranged to protrude outwardly from the botto...

Ligature systems retain an arch wire within a slot of an orthodontic bracket. According to some embodiment, the ligature system retains an arch wire within a slot of an orthodontic bracket by means of a retaining element which is capable of being unidirectionally mechanically locked within the slot of the orthodontic bracket to retain an arch wire therewithin. The retaining element may comprise a pair of opposed outwardly projecting retaining edges. In some embodiments, the retaining element comprises a planar or curved retaining plate. The ligature system may include a central block in which the retaining plate is embedded such that the retaining edges extend outwardly therefrom. The ligature system may also include spike protruding outwardly from such central block so as to engage with the arch wire positioned subjacently thereto. In some embodiments of the invention, the retaining element is integral with the arch wire, while in other embodiments of the invention, the retaining element is integral with the slot in the orthodontic bracket. A dispenser may also provided according to the invention for dispensing individual ligature systems.
Description
technical field [0001] The present invention relates generally to the field of orthodontics. In a particularly preferred embodiment, the present invention relates to a ligating system and method for an orthodontic bracket to releasably secure an archwire to the orthodontic bracket. Background technique [0002] This application is based upon and claims the benefit of priority from US Provisional Application Serial No. 60 / 721,487, filed September 29, 2005, the entire contents of which are hereby incorporated by reference. [0003] Orthodontic brackets move teeth by transmitting force from an archwire (or other external device) to one or more teeth. Typically, a bracket is strapped to the tooth, and an archwire is inserted into the slot of the bracket. The wire is then tied to the bracket with a binding wire. The bending of the arch wire or other external device creates a force in the arch wire which is transmitted to the bracket and further to the tooth. [0004] The bott...
